Abstract

The invention provides an aero-engine blade scribing method, a blade scribing system and a computer readable storage medium, and belongs to the field of aero-engine blade manufacturing and detection.The method comprises the steps that a current blade part is scanned, and a measurement point cloud of the current blade part is obtained; meshing the digital-analog model of the current blade part to obtain a digital-analog point cloud of the current blade part; matching the measurement point cloud with the digital-analog point cloud to obtain a rotation matrix and a translation vector for converting the measurement point cloud and the digital-analog point cloud; extracting a point set of to-be-scribed features in the digital-analog model; in combination with the rotation matrix and the translation vector, mapping the to-be-lineated feature into a real lineation feature in a point cloud space where the measurement point cloud of the current blade part is located; and the current blade part is subjected to scribing operation based on the real scribing features. By means of the treatment scheme, the technical problem of high-precision scribing on the irregular blade is solved, and the scribing method is flexible, easy to operate and easy to implement.

Description

technical field [0001] The invention relates to the technical field of manufacturing and testing of aero-engine blades, in particular to an aero-engine blade scribing method, an aero-engine blade scribing system and a computer-readable storage medium. Background technique [0002] Before vibration testing of aero-engine blades, strain gauges for data collection need to be pasted on specific parts of the blade. The accuracy of the pasting position of the strain gauge will affect the accuracy of the detection data, so the test system has high requirements on the position accuracy of the pasting of the strain gauge. [0003] Due to the complex shape and variety of aero-engine blades, the production of special tooling and inspection tools to determine the location of the strain gauges is long and costly, which cannot meet the actual inspection needs. The current method is to manually use a ruler and a marker to measure the distance from the sticking site to the reference, and t...
